2. BIAS Drop Mute  
If BIAS terminal (Pin 20) voltage becomes 0.7V (Typ) or less, output of all channels turns OFF.  
Please set it to a minimum of 1.3V for typical use.  
(However, the mute function doesn't work for CH2 when CNT=High. )  
3. PREVCC Drop Mute  
If PREVCC terminal voltage becomes 3.8V (Typ) or less, output of all channels turns OFF.  
If PREVCC terminal voltage becomes 4.0V (Typ) or more, output of all channels turns ON.  
4. Thermal shutdown circuit (TSD)  
Thermal shutdown circuit is designed to turn off output of all channels when the junction temperature (Tj) reaches 175°C  
(Typ) (with 25°C (Typ) hysteresis).  
5. Regulator  
Output voltage of the regulator (VREGOUT) is set according to the following expression.

VREGOUT VREGP   
R2  
Please disable the oscillation prevention beforehand, and use the capacitor connected between the regulator output  
(VREGOUT) and PREGND after confirming parameters such as temperature characteristics in actual operation.  
The power supply voltage fluctuation described in the Electrical Characteristics is obtained when VREGOUT is 5V.  
Please note that fluctuation bands increase from the described values if VREGOUT is set to a value bigger than 5V.

6. Input Sequence  
Figure 5. Input sequence  
Please use the below formula to determine the power supply voltage and the voltage for each input terminal.  
PREVCC POWVCC1, POWVCC2, BIAS, MUTE, CNT, IN1, IN2-1, IN2-2, IN3, IN4  
There is no special rule for power-up sequence if inputs are within the range of the above formula.  
It is not recommended that terminal voltage for BIAS, MUTE, CNT, IN1, IN2-1, IN2-2, IN3, and IN4 exceed PREVCC  
voltage.  
If these voltages exceed PREVCC, overcurrent is generated in the internal ESD protection diode. (refer to Figure 6)

Operational Notes  
1.  
Reverse Connection of Power Supply  
Connecting the power supply in reverse polarity can damage the IC. Take precautions against reverse polarity when  
connecting the power supply, such as mounting an external diode between the power supply and the IC’s power  
supply terminals.  
2.  
Power Supply Lines  
Design the PCB layout pattern to provide low impedance ground and supply lines. Separate the ground and supply  
lines of the digital and analog blocks to prevent noise in the ground and supply lines of the digital block from affecting  
the analog block. Furthermore, connect a capacitor to ground at all power supply pins. Consider the effect of  
temperature and aging on the capacitance value when using electrolytic capacitors.  
3.  
4.  
Ground Voltage  
Ensure that no pins are at a voltage below that of the ground pin at any time, even during transient condition.  
However, pins that drive inductive loads (e.g. motor driver outputs, DC-DC converter outputs) may inevitably go  
below ground due to back EMF or electromotive force. In such cases, the user should make sure that such voltages  
going below ground will not cause the IC and the system to malfunction by examining carefully all relevant factors  
and conditions such as motor characteristics, supply voltage, operating frequency and PCB wiring to name a few.  
Ground Wiring Pattern  
When using both small-signal and large-current ground traces, the two ground traces should be routed separately but  
connected to a single ground at the reference point of the application board to avoid fluctuations in the small-signal  
ground caused by large currents. Also ensure that the ground traces of external components do not cause variations  
on the ground voltage. The power supply and ground lines must be as short and thick as possible to reduce line  
impedance.  
5.  
Thermal Consideration  
Should by any chance the power dissipation rating be exceeded the rise in temperature of the chip may result in  
deterioration of the properties of the chip. The absolute maximum rating of the Pd stated in this specification is when  
the IC is mounted on a 70mm x 70mm x 1.6mm glass epoxy board. In case of exceeding this absolute maximum  
rating, increase the board size and copper area to prevent exceeding the Pd rating.  
6.  
7.  
Recommended Operating Conditions  
These conditions represent a range within which the expected characteristics of the IC can be approximately  
obtained. The electrical characteristics are guaranteed under the conditions of each parameter.  
Rush Current  
When power is first supplied to the IC, it is possible that the internal logic may be unstable and inrush current may  
flow instantaneously due to the internal powering sequence and delays, especially if the IC has more than one power  
supply. Therefore, give special consideration to power coupling capacitance, power wiring, width of ground wiring,  
and routing of connections.  
8.  
9.  
Operation Under Strong Electromagnetic Field  
Operating the IC in the presence of a strong electromagnetic field may cause the IC to malfunction.  
Testing on Application Boards  
When testing the IC on an application board, connecting a capacitor directly to a low-impedance output pin may  
subject the IC to stress. Always discharge capacitors completely after each process or step. The IC’s power supply  
should always be turned off completely before connecting or removing it from the test setup during the inspection  
process. To prevent damage from static discharge, ground the IC during assembly and use similar precautions during  
transport and storage.  
10. Inter-pin Short and Mounting Errors  
Ensure that the direction and position are correct when mounting the IC on the PCB. Incorrect mounting may result in  
damaging the IC. Avoid nearby pins being shorted to each other especially to ground. Inter-pin shorts could be due to  
many reasons such as metal particles, water droplets (in very humid environment) and unintentional solder bridge  
deposited in between pins during assembly to name a few.

Operational Notes - continued  
11. Unused Input Terminals  
Input terminals of an IC are often connected to the gate of a MOS transistor. The gate has extremely high impedance  
and extremely low capacitance. If left unconnected, the electric field from the outside can easily charge it. The small  
charge acquired in this way is enough to produce a significant effect on the conduction through the transistor and  
cause unexpected operation of the IC. So unless otherwise specified, unused input terminals should be connected to  
the power supply or ground line.  
12. Regarding the Input Pin of the IC  
This monolithic IC contains P+ isolation and P substrate layers between adjacent elements in order to keep them  
isolated. P-N junctions are formed at the intersection of the P layers with the N layers of other elements, creating a  
parasitic diode or transistor. For example (refer to figure below):  
When GND > Pin A and GND > Pin B, the P-N junction operates as a parasitic diode.  
When GND > Pin B, the P-N junction operates as a parasitic transistor.  
Parasitic diodes inevitably occur in the structure of the IC. The operation of parasitic diodes can result in mutual  
interference among circuits, operational faults, or physical damage. Therefore, conditions that cause these diodes to  
operate, such as applying a voltage lower than the GND voltage to an input pin (and thus to the P substrate) should  
be avoided.  
Figure 14. Example of hic IC scture  
13. Ceramic Capacitor  
When using a ceramic capacitor, determine the dielectric constant considering the change of capacitance with  
temperature and the decrease in nominal capacitance due to DC bias and others.  
14. Area of Safe Operation (ASO)  
Operate the IC such that the output voltage, output current, and power dissipation are all within the Area of Safe  
Operation (ASO).  
15. Thermal Shutdown Circuit (TSD)  
This IC has a built-in thermal shutdown circuit that prevents heat damage to the IC. Normal operation should always  
be within the IC’s power dissipation rating. If however the rating is exceeded for a continued period, the junction  
temperature (Tj) will rise which will activate the TSD circuit that will turn OFF all output pins. When the Tj falls below  
the TSD threshold, the circuits are automatically restored to normal operation.  
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no  
circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from  
heat damage.

Precaution on using ROHM Products  
1. Our Products are designed and manufactured for application in ordinary electronic equipments (such as AV equipment,  
OA equipment, telecommunication equipment, home electronic appliances, amusement equipment, etc.). If you  
intend to use our Products in devices requiring extremely high reliability (such as medical equipment (Note 1), transport  
equipment, traffic equipment, aircraft/spacecraft, nuclear power controllers, fuel controllers, car equipment including car  
accessories, safety devices, etc.) and whose malfunction or failure may cause loss of human life, bodily injury or  
serious damage to property (“Specific Applications”), please consult with the ROHM sales representative in advance.  
Unless otherwise agreed in writing by ROHM in advance, ROHM shall not be in any way responsible or liable for any  
damages, expenses or losses incurred by you or third parties arising from the use of any ROHM’s Products for Specific  
Applications.

2. ROHM designs and manufactures its Products subject to strict quality control system. However, semiconductor  
products can fail or malfunction at a certain rate. Please be sure to implement, at your own responsibilities, adequate  
safety measures including but not limited to fail-safe design against the physical injury, damage to any property, which  
a failure or malfunction of our Products may cause. The following are examples of safety measures:  
[a] Installation of protection circuits or other protective devices to improve system safety  
[b] Installation of redundant circuits to reduce the impact of single or multiple circuit failure  
3. Our Products are designed and manufactured for use under standard conditions and not under any special or  
extraordinary environments or conditions, as exemplified below. Accordingly, ROHM shall not be in any way  
responsible or liable for any damages, expenses or losses arising from the use of any ROHM’s Products under any  
special or extraordinary environments or conditions. If you intend to use our Products under any special or  
extraordinary environments or conditions (as exemplified below), your independent verification and confirmation of  
product performance, reliability, etc, prior to use, must be necessary:  
[a] Use of our Products in any types of liquid, including water, oils, chemicals, and organic solvents  
[b] Use of our Products outdoors or in places where the Products are exposed to direct sunlight or dust  
[c] Use of our Products in places where the Products are exposed to sea wind or corrosive gases, including Cl2,  
H2S, NH3, SO2, and NO2  
[d] Use of our Products in places where the Products are exposed to static electricity or electromagnetic waves  
[e] Use of our Products in proximity to heat-producing components, plastic cords, or other flammable items  
[f] Sealing or coating our Products with resin or other coating materials  
[g] Use of our Products without cleaning residue of flux (even if you use no-clean type fluxes, cleaning residue of  
flux is recommended); or Washing our Products by using water or water-soluble cleaning agents for cleaning  
residue after soldering  
[h] Use of the Products in places subject to dew condensation  
4. The Products are not subject to radiation-proof design.  
5. Please verify and confirm characteristics of the final or mounted products in using the Products.  
6. In particular, if a transient load (a large amount of load applied in a short period of time, such as pulse. is applied,  
confirmation of performance characteristics after on-board mounting is strongly recommended. Avoid applying power  
exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect  
product performance and reliability.  
7. De-rate Power Dissipation (Pd) depending on Ambient temperature (Ta). When used in sealed area, confirm the actual  
ambient temperature.  
8. Confirm that operation temperature is within the specified range described in the product specification.  
9. ROHM shall not be in any way responsible or liable for failure induced under deviant condition from what is defined in  
this document.  
Precaution for Mounting / Circuit board design  
1. When a highly active halogenous (chlorine, bromine, etc.) flux is used, the residue of flux may negatively affect product  
performance and reliability.  
2. In principle, the reflow soldering method must be used; if flow soldering method is preferred, please consult with the  
ROHM representative in advance.  
For details, please refer to ROHM Mounting specification
